PONTOON-SUPPORTED DERRICK.

-App1ication filed August 22,1922. Serial No. 583,547.

To all whom it may concern Be it known that I, CHARLES L. LoNsrNo- ER, acitizen of the United States, residing at VValhonding, in the county ofCoshocton, State of Ohio, have invented a new and usefulPontoon-Supported Derrick; and-ll do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the. art to which it appertains to make and usethe same.

The invention relates to pontoon supported derricks, and-has for itsobject to provide a derrick particularly adapted for use for drillingoil wells, said derrick being of a knock-down type, thereby allowing theSame to be stored within the pontoon.

A further'object is to provide a derrick support comprising spacedpontoons in parallel relation to each other, said pontoons beingprovided with yoke members for rigid- 1 connecting the pontoonstogether. The (l errick is supported centrally between the pontoons withits supports and braces attached to the upper sides of the yokes. Thepontoons form means for preventing swaying of the derrick during thedrillingor casing driving operation and also forming a support for thederrick, which when the derrick is disassembled, and the pontoonsseparated, may pass through narrow laces such for instance as canals,under brldges, or may be easily shipped over land.

A further objectv isto provide one end of one of the pontoons with anengine adapted to be utilized during a well drilling operation. Thepower for said engine is obtained from a pipe leading to a boilerlocated on a separate pontoon located at a remote point from thederrick,thereby obviating explosions and fire incident to the well drillingoperation.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawing:-

Figure 1 is a side elevation of the pontoon supported derrick, showing aboiler supported on a separate pontoon.

Figure 2 is a top plan View of the device.

the operation.

Figure 3 is an end-view of the pontoon showing a portion of the derrick.

Figure 4 is a,detail perspective view of one end of one of the yokes.

Referring to the drawings, the numeral 1 designates spaced pontoonswhich are in parallel relation to each other. The pontoons 1 are held inspaced parallel relation by means of yokes 2, which extend transverselyof the pontoons. Each yoke 2 comprises a transversely disposed bar 3,which engages the upper sides of the pontoons 1 and segmentally shapedmembers 4, which engage under the bottomsof the pontoons and have theirends detachably connected at 5 and 6 adjacent the inner and outer'sidesof the pontoons, thereby rigidly holding the pontoons in spaced parallelrelation.

versely disposed bars 3 is a derrick 8 of a knock-down type, whichderrick is centered over the space 9 between'the pontoons 1 and is alsocentered in relation to the ends of the pontoons, thereby preventinglisting of rick, which supporting base will prevent.

swaying of the derrick, and at the same time when the derrick isdisassembled and placed in one of the holds 12 of the pontoons throughthe hatches 13 that is, after the yokes 2 have also been disassembledand stored in the holds 12, the pontoons may be easily moved throughnarrow places, such for instance as canals, or under bridges, andparticularly through shoal-water, and if so desired shipped over land.

Disposed on one end of one of the pontoons 1 is a steam engine 14, whichengine may be utilized for operating mechanism during the drilling orcasing driving or pulling operation. The engine 14 is'supplied withsteam from a boiler 15 located on a pontoon 16, which is remote to thederrick 8, thereby preventing ignition of gases and consequent explosionand fire, the ignitinn of the gases being caused by fire under Detach-'ably connected at 7 to the central transthe boiler 15. Steam passes fromthe boiler 15 to the engine 14 throu h the pipe 17, which pipe passesover a sma l pontoon 18 which is connected at 19 to the pontoon 16 andto one of the pontoons 1. Pontoon 18 forms a walkway over which workmenmay pass to and from the pontoon 16.

From the above it will be seen that pontoon supported derrick isprovided which is simple in construction, and that may be easily shiftedor moved bodily as a whole from place to place or may be easilydisassembled for shipping or storage purposes, and that the pontoon willprevent swaying or moving of the derrick, and at thesame time when thederrick is disassembled and stored within the pontoons, said pontoonsmay be passed t h rough canals and other narrow waterways.

The invention having been set forth what is claimed as new and useful isl 1.- The combination with a well derrick, of means for'supporting saidderrick on water, said means comprising a base, said base being formedfrom spaced pontoons in parallel relation to each other, said pontoonshaving their upper sides fiat and their under sides convexed,transversely disposed yokes connecting said pontoons together, saidyokes comprising bars engaging the upper fiat sides of the pontoons,segmentally shaped members arching the undersides of the pontoons, theends of said segmentally shaped members being detachably connected tothe bars adjacent the sides of the pontoons.

2. A well drilling derrick adapted to be alle relation to each other, te upper side of the pontoons being fiat, transversely dillposed barsdisposed on the upper flat sides of the pontoons and extending acrossboth pontoons, U-shaped bands arching the undersupported on water,spaced ontoons in parsides of the pontoons and having their endsdetachably connectedto the bars adjacent the opposite sides of the.pontoons, said derrick being centrally disposed on the base formed bythe pontoons and detac-hably con-
